Control System Tuning with systune
Obtain a state-space linear system model from the frequency response estimation result.
Using an option set for the ssest function, set the numerical search method used for this
iterative parameter estimation as the Levenberg-Marquardt least-squares search.
Estimate a state-space model with four states and a period of 4e-6 seconds.
optssest = ssestOptions('SearchMethod','lm');
optssest.Regularization.Lambda = 0.1;
sys_singletune = ssest(estsys,4,'Ts',4e-6,optssest);
In order to tune all three PI controllers in the PMSM FOC model, we need to construct a
control system, as shown in the following block diagram.
